The ad attacks Buchanan for accepting $15,450 in contributions from the National Rifle Association. Buchanan — who represents Sarasota and Bradenton in Congress — is the only Florida representative Giffords’ group has targeted so far.

The Parkland shooting that killed 17 students and staff and subsequent demonstrations have thrust gun control into the midterm elections.

That ad — which aired in the Miami, Palm Beach, Orlando and Tampa Bay markets — highlighted Scott’s support of a law restricting doctors from asking patients about firearm ownership.

Isabelle James, political director for Giffords, said the group is planning to spend about $5 million in elections this year, targeting incumbents in competitive districts with suburban voters who favor tighter restrictions on guns.

“We are looking at races where we really believe this issue is going to make a difference, where it’ll rise to the top of the list for voters,” James said.

It’s “quite likely” Giffords will spend on Florida’s high-profile Senate race, and U.S. Rep. Mario Diaz-Balart, a Miami-Dade Republican, is also on the group’s radar, James said. Former judge Mary Barzee Flores is challenging Diaz-Balart, who hasn’t faced a serious Democratic challenger since 2008.

Former Democratic U.S. Rep. Gabrielle Giffords — who was wounded during a mass shooting in Arizona — founded the political committee in 2013 in the weeks following the shooting at Sandy Hook Elementary School.

Buchanan represents the cities of Bradenton and Sarasota in Congress, a district that Trump won by 11 percentage points. He’s being challenged by Democrat David Shapiro, a personal injury attorney who’s been endorsed by Giffords’ group.

The ad tells viewers “the NRA owns Vern Buchanan’s vote.”

“He’s been bought and paid for,” the ad proclaims.

The group has purchased similar ads in nine other competitive congressional races across the country.
